What is the css screen resolution in the browser on Apple iMac 27?

Question

css

As far as I know, the resolution of poppies is 5120x2880. But as I understand it, scale is used in browsers.
In general, I would like to know how much exactly this is in css pixels.

You can view it by typing in the browser console, if possible:

window.innerWidth
window.innerHeight

Answer 1

In general, I put it incorrectly (nonsense, apparently with a binge).
The maximum resolution on the iMac 27 5K is 5120x2880.
So it's the same in the browser.
But of course, no one uses such a resolution, but they use 2560x1440, because. too small for 27 inches.
This is me to the fact that there is no special point in sharpening your sites under 5120, 2560 is enough.
